The url check only looked for an http:// or https:// prefix. Several
shapes passed it and then left the source dead at login time: no host
("https://"), a bad port, surrounding whitespace (sent as %20 and
answered 404), and any query or fragment. The resolver appends
"?username=…&serverId=…" to the url as a string, so an existing query
swallows those parameters and a fragment hides them from the request
entirely. Each loaded green, and every login from that source failed.
The url is now parsed and must be http or https with a host, no query,
no fragment and no surrounding whitespace. Load and LoadNano share the
check. The shipped LittleSkin default and plain http:// endpoints, such
as a same-host root on loopback, still load.
The new test feeds each rejected shape to LoadNano. Against the previous
prefix check, six of the seven load; only ftp:// was refused.
